I started with these tires on my clone at the beginning of the year. The ones I got are too soft for clone racing. Besides, the only size rear tire offered is a 7.10 and you need a 6.0 or less for the clone. I am not sure, but if you use these you will need the harder compound in my opinion.

When I switched from the Conti's to a new set of Bridgestone 4.5 and 6.0 YHC compound I am up front again.

Comet Kart has a package deal on these tires._________________Kerry Wilson

Limited amount available and like Kerry said too big and too soft. We both tried the softer Conti and found out we don't have the horsepower to make them work. I tried every tire pressure from low to high just to much grip and in my case side wall flex made the kart bounce. I had some smaller Bridgestones I was going to try last race but due to the weather never got a chance. Mine are softer than Kerry and might still have to much gip. The only way I see the soft big tires working on our Clones is when the cord is showing and the rubber is wore out!
